SFECIFCATION forming part of Letters Patent No.342,311, dated May 18, 1886.

Application filed Nnvcinbcrll, 1885. Serial No. lil.

To aZZ whom it may concern:

Be it known that I, JAMES F. WrNoHnLL, a citizen of the United States, residing at Springfield,in the county of Clark and State of Ohio,have invented certain new and useful Improvements in Crushing and Grinding Mills, of which the following isa specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in crushing and grinding mills, and it is designed to crush and reduce bark, bones, and other substances, and to reduce cereals of various kinds; and it has for its objects, first, to provide a mill with a 'erusher and a grinding-head, so locked together that the motion of one is transmitted to the other, and with means to maintain this engagement and of such a nature as will not become dislodged and caught in the working parts of the mill; second, to provide a mill with a crusher and a grindinghead locked therewitlnan d with a sleevelocked to the crusher, whereby motion received from the head will be transmitted by the crusher to the sleeve; third,to provide a mill with a forcefeed device or devices, which will act to posi tively feed the material from ahopper to or toward thegrinding mechanism proper; fourth, to provide a mill with agrindinghead mounted so as to maintain a set position with respect to the other grinder by frictional contact with its niountings.

In the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate corresponding features, Figure l represents a `vertical sectional View ofthe casing, generally, of the machine, showing a portion ofthe mechanism in section and a portion in side elevation; Fig. 2, a dctached face view of one of the segmental grinding-plates; Fig. 3, aplan view ofthe machine with the upper portion of the casing and the feeding mechanism and hopper removed; Fig. 4, a detached perspective view of the combined feederoperating pulley and sleeve; Fig.

5, a like view of the crusher; Fig. G, a detached view of the outer face of one of the crushing-lugs; Fig. 7 a vertical sectional view through a part of the lower portion of the casing and the door; Fig. 8, an enlarged detached partial edge and sectional View of the stationary grindinghead7 sh owing that part of (No model.)

the main frame which is in immediate juxtaposition; Fig. 9, a partial side elevation of the hopper-box, the feed-box, andthe upper portion of the casing, showing the means of connecting the same together; Fig. 10, a side elevation of the bracket for supporting one side of the stationary grindinghead, showing also the adjacent portion of the main frame and the adjusting-screws; Fig. l1, adetached view of the bolts for binding the casing, the feedbox, and the hopper together; Fig. 12, a de tached plan view of the feeding mechanism; Fig. 13, a transverse section of the same on the line w a, looking in the direction of the arrow; Fig. 14, a like section on the line 1/ y, looking in the opposite direction; and Fig. 15, a longitudinal sectional view of the feedroller.

The letter A designates the sills, to which the standards B are firmly secured, and the letter' O the general frame of the machine, which is bolted or otherwise secured to the said standards, and which consists of east-iron and terminates ina shaft-support, D, at one end, and in a. semicircular shell or casing, E, at the other end. The lower portion of the casing E is provided with a discharge-opening and a detaehabledoor, F, having a lug on its upper inner end, which engages the casing, and a similar lug at the lower inner end,which also engages the casing, as seen in the lower right-hand portion of Fig. l, and in detail in Fig. 7. The door is fnrther provided with a lip and set-screw, G, by means of which its position with respect to the casing is maintained, the screw tending to bind the door closer to the casing asitis screwed more tightly. The intermediate portion of the frame C is hollowcd out to form a chamber, H, having 'one or more longitudinal recesses or grooves,

l, which serve the function of arresting the escape of corn cobs, and of holding them against the action of the Crushers when the machine is organized for reducing large substances.

The letter J designates the main shaft or arbor of the machine, which extends from end to end, and is supportedin suitable boXesatK and L, and which carries a balance-wheel, M, and is longitudinally adjustable by means of an adj usting device, now about to be described. This device consists of a yoke, N, pivotally IOO mounted at one end to the end of the machine, and secured at the other bya Wooden .orother fragile pin, O,whereby it will yield orbreak in case any'hard substance-*as a stoneis accidentally thrown into the machine. This yoke has a screw-threaded opening, in whiclrworks an adjusting-shaft correspondingly threaded and provided with a hand-wheel, P, the pe- Ariphery whereof is provided with notches graduated with respect to the number of threads to the inch on the shaft,whereby a rotation of one or more notches will adjust the space between the grinding-surfaces to a predetermined distance or quantity. To the lower part of the yokeis pivotally mounted a weighted locking-dog, Q, guided by lugs R at its in ner `end,.aud engaging, the notched wheel vat the other. A. metallic block, S, and .an antifriction washer, T, are interposed between the main shaft J and the adj Listing-shaft, the washer being composed of some smooth and lasting substance. Secured to the main shaft, in the present instance by a pin, U, is a grinding-head, V, of disk form, the said pin engaging its hub. On the `face the head is provided with a conical boss,\V, having` a curved exterior and provided with an offset on its face, so as to present twodistinct vertical planes when in the position shown in Fig.

The letter X designates a sleeve or cylindrical Crusher mountedupo'n the shaft J, and constructed atboth ends with offsets adapted to register, respectively,with the offset on the face of the boss NV. The exterior of the crusher is provided with aseries of lugs, whose sides are -fashioned ,each into two surfaces. The angle of the said surfaces to each other on one sideis slight, while the angle offrhe surfaces on the other side is increasedthe result of which is to feed the grain from the chamber H into the space between the grinding-surfaces morel or less rapidly, according to the position in which the crusher is placed, for

when the greater angle of the lugs is placedr toward the boss W thegrain is fedmore rapidly from theA chamber and into the said space than when the lesser angle isplaced toward the `said boss.

the shaft J at this point. The sleeve `hasits end adjacent to the Crusher provided with an offset adapted to registerwiththat inthe endl of the .orusl1er, whereby rotary motion im parted to the crusher bythe,revolvin g grinding-head will rotate the sleeve. -The peculiarv By the above arrangement of offsets I am en abledto turnthe crusher end for end, and yet rotate it in veither direction. This also avoids Also mounted upon-the shaft J is the sleeve Zhaving a bearing at A inf the main frame, thereby serving to supportjV the necessity of resorting to set-screws or anything of that nature which is liable to become disconnected and get caught in the working l parts of the machine, thereby causing serious injury, and sometimes exposing the operator to danger.

The'letter1 D' designates the stationary grinding-head, which, like the rotating` grindinghead, is of disk form. It is provided at diamctrical points with bosses E', integrally formed therewith, and in each of these bosses is fitted somewhat loosely a trunnion-piu, F',

,which also extend, the one into au enlargement, G', formed integrally with the frame, and the other into an adjustable bracket, H', secured to the main frame by a bolt,1, or other equivalent device, in such wise as to admit of adjustment to .and from the rotating grindinghead. An adj usting-screw,J',passing through a lu@ K' Yextendin from the frame serves to V l sary to operate the adjusting-wheel, force the rotatinghead againstl the stationary head, and

.- thus cansey the latter to change its position until thetwo heads agree. lThe wheel is then Yturned back until theproper space is had be- -tween the heads for grinding purposes.

frictioubetween the trunnion-pins and the holesin the bosses on the stationary head and in the brackets prevents` the head fromlosing its adjusted position. The object of adjusting vvthe bracket H', as above indicated, is to adjust the stationary head with respect to the rotating-head in case the position ofthe main shaft should vary from a right angle to the Astationary headon account of shifting later- :ally in a slightdegree.

This adjustment 0f the stationary head is also of importance in .setting up the machine, as it saves the expense ofthe finer workmanship, which would ,otherwise be required Vto secure the proper relative vposition of these heads. Inasmuch as the bracket G' is a part of the mainframe .of the machine, and inasmuch as thebracket vH' isirmly secured by the bolt l' to the said frame after any given adjustment, and -inasvmuch as .the trunnion-,pins F' are prevented from moving in said brackets by the setscrews L', practically speaking', the saidpins vbecome `tirinly secured to the frame.

The said head .D' 'is provided with a central openingand isythickened about the opening, and

hasseveral ribs M', projecting inwardly into .the opening, which act in conjunction with the similar ribs, N', projecting from the boss WA These ribs approach each other in thedirection of the grinding-plates, and their function The ICO

is to draw and somewhat reduce to a finer state the material under operation from the chamber H.

The letter O designates the grinding-plates, the same being preferably constructed of castiron and of segmental form, and being pro vided on their inner faces and near the periphery with a series of V-shaped ribs or teeth,P', as also with a series of grinding studs or protuberances, Q', preferably of the form shownthat is, with curved and sti aight sides and recesses R', the latter affording additional grinding-edges. The lugs Sserve asacontinuation of the ribs M' and N', and thus assistin drawing the material between the grinding-plates. These plates are bolted to the grinding-heads in any convenient manner.

The letter T indicates the upper portion of the casing, a part of :which envelops the grinding mechanism, and the other part, T, constitutes a box, which ts over and conducts the grain and cobs, as the case may be, to the chamber H.

The letter U' designates the feeder-box, which fits upon the portion T" of the casing, and is provided with ribs V' and a partition, W', which serve to support a slide or cutoff, X. This slide has adepending wing, Y',which serves to clear the feed-wheel of any undue accumulation, and is beveled olf on one side, against which bevel a bracket, Z', is adapted to beimpinged by a screw and thumb-nut, Z", for the purpose of holding 4the slide in any fixed position. The opposite edge is rabbeted and travels beneath a lip, a. The lower side of the box has notched lugs Z1, which engage the upper edge of the portion T" ofthe casing and maintain the box in position. i

The letter C indicates a bearing projecting from the box, and d, a bearing formed on the partition W'. In these bearings the shaft of the feeding-roller e is mounted, and through the clutch f and the .band -wheel g (whose hub has a corresponding clutchsurface) rotary motion is imparted to the said roller, a band, 7L, being employed to connect the wheel g with the pulley B. The feedingroller is provided on its periphery with analternating series of longer and shorter grooves, slightly deeper at one end,z, than at the other, as seen in Fig. 15, the ribs or edges left between the grooves serving to effect a forced feed of the grain. The box is also provided with inclined inner walls,j, which guide the grain to the roller, and which reduce the space between the roller and the walls proper of the box. These inclined walls -taper from the roller in the direction in which the slide is opened ,thus increasing the width in the space, as well as the length thereof, for the passage of the material as the slide is drawn out.

The letter k designates the hopper, which ts upon the box U' and supplies the material to be acted upon. This hopper is provided with a hinged flap, Z, which serves no purpose in the machine as organized in this application, but which serves the purpose of preventing the broken corn-cobs (or the grain when the cobs are ground with the grain on them) `from being thrown up by the machine, as described in my application filed February 27, v1886, Serial No. 193,464., for improvements in crushing and grinding mills.

The portion T" of the casing has several recesses, r, iu the upper edge, and the feedingbox U' has lugs s and notches t, which lit each other and serve to keep them in proper relative position. The hopper also has lugs a, which engage the notches of the boxes or the notches of the portion T, as the case may be, for the same purpose. Should it become necessary, however, to bind the several structures together, as seen in Fig. 9, then I engage a bolt, o, with a 1ug,fw, on the hopper, and pass a bolt, m, through an eye in the said bolt o, and through an opening in the main frame, and apply a nut. Vhen the feeding-box U is omitted, I secure the bolt o directly to the main frame, by passing it through a hole, as seen at Fig. 9, by a bolt similar to the bolt or, but very much shorter.

By reason of the construction of the crusher and the sleeve and the boss with which it engages the machine may be successfully operated in either direction, and by reason of the V-shaped or saw-tooth configuration of the grinding-teeth the rotating grinding'head may be run in either direction, and thus keep the teeth sharp and increase the period of their usefulness. The crushinglugs, having two faces on each side, are, therefore, capable of performing their function, no matterin which direction the crusher-sleevc is rotated.

As already stated, the function of the crusher and its lugs is to convey the grain from the chamber H to the grinders when cereals are being ground.

In order to prevent the material from getting between the stationary grinding-head and the interiorof the casing Eand T', and thence out of the dischargespout without being duly acted upon by the grinding-plates, I provide a rubber or other yielding band,l0, and se- IIO cure it to the said head in any convenient manner, as by stretching it over the nuts of the bolts which hold the plate to the head, as seen in Figs. 1 and 8. y

The devices herein shown and described, but not specifically claimed, and which have peculiar reference to the mill in its crushing capacity, form the subject-mattei' of claimsin my application filed February 27, 1886, Serial No. 193,464, for crushing and grinding mills.
